Two masked gunmen on the Caribbean island of St. Kitts held up a tour bus on the island's main road Sunday, robbing 16 cruise ship passengers from the Celebrity Mercury of their cash and cameras, authorities told the Associated Press. No one was injured.

Police say the passengers were traveling to the Brimstone Hill Fortress, a park popular with visitors. According to the AP, park manager Joseph Woodley told local radio that the robbers blocked the road with a fallen tree. When the bus driver got out to clear the way, they emerged from bushes and robbed the tourists before disappearing back into the woodlands.
